the ride is not over yet. plummets, another dose of their. four nights of rioting, and officials say they will stop the violence that has spread against weakened. >> we need to restore the sense of responsibility across our society, in every town, every est.. >> inside the world's largest refugee camp, aid has long been the only relief.

welcome to our viewers on pbsbsn americicananlslsararndndhe glgle.e. it is a ride which is making even seasoned market veterans reach for something solid. markets from the u.s. to europe took another plunge. this time it was on concern of french and debt. in britain, the ftse lost 3% of its value, and here in the u.s., the dow jones are -- the dow jones fell 300 points. >> it did not last long. the gains from tuesday's rally evaporated as u.s. stock markets followed europe's leloir. the catalyst -- fiers on at the new york stock exchange. for most of the day, the dow jones industrial was down 300

points. >> so much is based on psychology and human emotion, and people are pulling the trigger first and thinking about it. they are nervous and scared. >> with the federal reserve of's and tim -- with the federal reserve's dam outlook on the economy rattling wall street, it was concerns -- dim outlook on the economy rattling wall street, it was concerns over europe there really sent the market lower. there are concerns that french debt will be downgraded. the nation's second-largest bank became the focus of much anxiety. shares fell and close at 14 percent down for the day. >> it is a question of whether in three months' time it will be downgraded.

there are other problems in the economy. i do think there is a major crisis in the euro zone. >> in america, banking shares fell, too, but for a different reason. investors once again showed it is fear driving these markets. bbc news, new york. >> for more on the dismal day in the markets and what is driving the slide, i am showing it by our guest from "the financial times of." alan thank you, for joining us. the fear factor. are there fundamental concerns about the economy? >> people are thinking very short term at the moment. people are getting into and out to stocks. the funny thing is the news that has driven s has the opposite effect of what you would have

imagined. the only real news of the last few days is the u.s. credit rating being downgraded. you would think that the dollar would fall. the opposite has happened. that fear has gone into other markets, the fear of downgrading in europe for example, and that has any effect their. all these are interconnected, but it is not mechanical. that is what is creating the uncertainty. >> let's talk about france. very bad day their. can this be traced back to greece. -- can this be traced back to greece? >> more generally, if there is a crisis of confidence in all euro zone that, because the news on that front the last week has been falling prices in spain and italy. there is also the channel of

contagion, that if the credit rating agencies are to downgrade, they might downgrade france as well. there are a variety of channels pushing in the same direction. >> what you think is the biggest threat to the global economy? the european debt crisis? >> yes, the european debt crisis. the u.s. downgrade was not good, but it has not started an immediate move for the dollar south, as you would have expected it to. the real threat is if the european problem does spread to spain. no one really knows if it has been sorted out in the medium term. the more worrying underlying issue -- the underlying problem, if you like. it is most likely in the euro zone. >> thank you for joining us. in england, there are thousands of extra police on the streets as they try to prevent a fifth

night of riots and looting. the prime minister has joined authorities in birmingham to call for control their after three men were run over. they were trying to protect the neighborhood from looters when police say they were deliberately driven over. a 32-year-old man has been arrested for murder. >> every scrap of evidence is needed. police believe this man is guilty of murder. >> the community pays their respect to the three men who were killed. the brothers and their friend. >> he was younger. >> he tried to revive his own son. >> someone from behind a said my son was lying behind me.

i tried to do cpr on my own son. my face in my hands were covered with blood. why? anything i would have done, i would also have asked harun. now my eldest, and they killed him. >> friends and neighbors are deeply angry. >> we need to stand together and fight for peace. >> exclusive footage given to the bbc shows the street just after the men were mowed down. 1 lies on the ground and a group gathers. >> i think they are dead. they are dead. >> this was filmed by a 13-year- old. >> they were just shaking. there were just lying on the st.. >> west midlands police believe

this may trigger more violence, but this time on a long or racial lines. >> if we are calm, i am confident the west midlands can get through this. for us, we can build trust between communities and we can move on with a sense of purpose. >> this footage is from all local sikh television station. it appears to show the tv crew giving the police a lift to chase after the suspected murderers. >> there you go. >> they are seen arresting a man, one of four people detained last night.

this afternoon, members of the community gathered around the league presenter from the tv. >> it is quite extraordinary. >> it is extraordinary, but in some ways it is incredibly uplifting. it shows they care about their neighborhood, their city, their country. >> a few hours ago, harun's father made up before a calm. >> please respect the memory of our loved ones by staying away from trouble. >> what people most want is for the violence to end and for everyone to remain calm. with so many people feeling so much anger, it would be easy for this to become another violent night.

bbc news, birmingham. >> today, prime minister david cameron declared a fight back was needed and a fight back is under way. he did pin the violence on a complete lack of responsibility in british society and vowed to restore values. it is an argument that will play out tomorrow in parliament with members call back from the summer recess. for more, i spoke with a member from downing street. hall -- how much of a test will this be for the camera and government? >> i think this statement is not likely to be a very great test, because what is striking this week is the degree of unity between rival political leaders in the face of this unprecedented level of violence. david cameron has been absolutely determined to

present this not as rioters taking on the government, but as looters taking on the people. not a political protest, but as criminality. so far, the main opposition party, the labour party, have backed him on that and have resisted the props from some in their ranks. there are bound to be voices in the house of commons that will criticize the prime minister for being away when this happened, for being slow to come back, for the police tactics being to stop, but in the main i suspect we're likely to see some statement of national unity against what we have seen this week. >> so, then the focus will be on why this happened rather than containing the violence? is that what you are saying? >> yes, although that debate has yet to take place. it is clear we are no longer

seen riot police in cities up and down inland. until we do not have jobs having to close early, until workers are not being sent home early to avoid being stuck in potentially difficult situations, no one sees the political value of having a debate over the causes of this or whether government spending cuts are part of the course. that debate, that division will take over from this united front. i am not quite sure how much we will see tomorrow. >> nick robinson, from downing street in london. thank you. in other news, protests in rome as prime minister silvio burlesque their met to discuss new austerity measures. -- silvio berlusconi. italy pledged last week to

balance the budget in 2013, a year earlier than planned. china's first aircraft carrier has begun its -- >>. they left their shipyard in northeast china. the move is likely to raise concerns over the country's rapid military buildup. opposition activists in serious and more than 20 have been killed by security forces, many in a central city. one activist said people were being arrested and fired upon trying to escape. meanwhile, international pressure is growing against the assad regime. the u.s. has announced sanctions on syria for largest commercial banks and their largest mobile phone operator. the white house spokesman says the world is watching stereo with horror. >> there is criticism aimed at

president assad for his heinous actions. it is not an accident. it is partly because we are all watching with horror what he is doing to its own people and we're working with our international partners to ensure that pressure continues to be placed and is ramp up on president assad. and we will continue to do that. >> for more on the growing chorus, i spoke to robin wright. so far, president assad does not appear to be listening to anybody. what effect our sanctions from the u.s. likely to back? >> they are actually for proliferation activities in the case of the banks and the relationship with corruption for the cell phone companies. this will not change the regime 's mind.

this is a critical week. kaine -- king abdullah, who is normally taking a background posture, has taken a very visible stand. the turkish prime minister met for four hours with president assad. the islamic world is taking the toughest actions. >> is this growing voice likely to give the u.s. more substance and will if allow a policy change? >> one question is whether the united states will formally ask president assad to step aside and say his legitimacy is no longer credible to any member of the international community. they are not quite seeing no. there is anticipation they may well be that.

it is hard to see how president assad will survive this politically. but the denoument will be playing now. >> why is the international community so reticent? why not syria? >> i think syria is a tough nut to crack. what else can the administration do in washington? the libyan option, using military force, is not one that appeals to anyone. syria borders israel, iraq, turkey, and it is a very strategic territory. there are also very important minority groups in syria who of not yet taken a stand against the assad regime. >> you say assad has been politically weakened by all this, but what is likely to happen if he does go? you mentioned civil war?

>> the striking thing about syria is the people have so far turn to peaceful civil disobedience. they have turned out in ever- larger numbers despite the brutality of the assad regime. it does not look like it is headed to civil war at the moment. as long as this goes on, it is dangerous. >> robin wright, thank you for joining us. >> thank you. >> still to come -- taking on the taliban. less than a week after 38 service members were killed in afghanistan, the u.s. commander there says those responsible have been hunted down. the libyan government has accused nato of killing 85 civilians in an air raid on the west side of the country. our correspondent was among journalists taken by the government to see destroyed

buildings east of the capitol, tripoli. e-mail find some of these images disturbing. -- you may find some of these images disturbing. >> under the fierce summer sun, they came to bury their dead. civilians, they told us, more than 20 in all at this mass funeral. the anger against nato was clear. at the side of the -- at the site of the hairs for itself, they were recovering the bodies, they told us, of 10 children. it is hard to know if nato did strike this area, exactly what the strategic value was. the libyan government is telling us there was no strategic value here, that it was purely a civilian target. >> data says it struck a site -- nato says is for the site that

was a staging area for pro- gaddafi forces. at the mortuary, they showed us about 30 bodies being -- about 30 bodies. most were of young men, about fighting age. we found this girl. >> there was no military camp. we were just living their. why did they attack us? >> her grief was a genuine. precisely how many civilians were injured is still unclear. bbc news. >> the u.s. says international forces in afghanistan have killed the taliban and surgeons responsible for shooting down a u.s. helicopter over the weekend. the statement by the

international security assistance force in afghanistan says multiple intelligence leads and tips from local citizens about the identity of those who shot down the chinook. >> the final homecoming. the military transport touches down at dover air force base, carrying the remains of 38 americans, some of them elite special forces. a sobering moment for the commander in chief who would spend more than an hour in private with grieving families before saluting the dead. the single biggest loss of life in america's longest war. investigators have sealed off the crash site while the wreckage of the downed helicopter is retrieved. today the americans may appoint a revealing that those responsible have themselves been killed. >> of approximately midnight on august 8, coalition forces killed the insurgents

responsible for the attack against the helicopter. this does not ease our loss, but we must and we will continue to relentlessly pursue the enemy. all across afghanistan, the insurgents are losing. >> the general said two insurgents were killed by an f- 16 air strike. but later the taliban suggested the man who had fired on the chinook was alive and fighting elsewhere. among the dead, two navy seals. some are being remembered publicly. >> i heard the doorbell rang. and i remember thinking, though, it is just a neighbor. i saw my father opening the door. and men coming in side -- inside in uniform. and there was this energy.

everything just drops out of your. address remember saying "no." -- i just remember saying "no." >> some question might the helicopter was making such a vulnerable landing given that u.s. lives were not under threat on the ground. these deaths opposed new questions about the afghanistan strategy at a time when the president is desperate to focus on problems here at home. it may not be a turning point as many americans had already concluded the war is unwinnable. bbc news, washington. >> in a new warning, experts say this since the beginning of the year, a harsh conditions in somalia have seen hundreds of thousands of people fleeing to

kenya. that has put a strain on relief camps already established since the civil war of the 1980's. >> for a few hours every day, the children of section m-6 can pretend they are like children everywhere. the play room cocoons them from a harsh world. the make believe houses they build are a million miles from the reality, and well-meaning aid workers encourage them to imagine a country that is largely a fiction. in fact, they were born here and they have never returned. >> would you like to go to somalia? >> the answer is no. their parents say is a bad place. this massive aid operation serves 300,000 people who fled

the somali conflict of the 1990's. they need help, but they are not starting. >> 3 of every four people you see have nothing to do with the current crisis. in some cases, they have been collecting rations for a decade and more. it is a graphic reminder there is a much deeper problem at work. >> it begs the question. is all this aid solving a problem or simply prolonging it? this refugee has been here since 1992 and has an answer, though not one for the faint hearted. >> let the aid stop, and then they will have to go back home. some will die, but others will have to find a solution. >> over the years, parts of the refugee camp have begun to look more and more like a town. there are markets, a mechanic,

even at juice maker. it has its own economy, driven in part by the aid that close in. they spend what they get at one shop with other traders. >> of course, it would be better to be in our own country. but there is work going on in somalia. >> and the failure to solve somalia's deep-seated crisis drives a new generation across the border. another mother building another shelter in this no-man's land of hopelessness. bbc news, kenya. >> that brings us to the end of today's broadcast. for all of us, and thank you for watching and see you back here tomorrow.

>> make sense of international news at bbc.com/news. >> funding was made possible by the freeman foundation of new york, stowe, vermont, and honolulu. newman's own foundation. and union bank. >> union bank has put its global financial strength to work for a wide range of companies. what can we do for you?
